Specification of Letters Patent.

To all whom it may concerm Be it known that I, FRED G. BELL, a citizenof the United States, residing at Alafication. v v

This invention relates to prime-motors and the principal objectoftheinventlon 1s to provide an improved method of operating prime motors andutilizingthe heat of the exhaust from asteam or internal combustionengine or the heat from the sun or other similar source of heat.

Another object of the invention is to provide an improved apparatus forcarrying out this method. p VViththe above and other obj ects'in vie theinvention consists in general of certain 'binations of parts as will behereinafter Q fully described, illustrated in the accompanying drawings,and specifically claimed.

In the accompanying drawings like charactors of reference indicate like.parts'in the several views, and the figure is a diagrammaticillustration of a plantfor carrying out this method.

In the embodiment of the invention herein set forth there is indicated aheater 10 of the type usually employed to heatfeed water for boilers.This heater. consists of a drum containing acoil of pipe ll and is incommunication with a suitable source of exhaust steam, gas, or the like,by means of a pipe 12, utilized fiuidafter passing through.

the'heater passes out of an exhaust pipe 13.

' Thishea'ter has its coil filled fulliof water and both its upper andlower ends are in communication respectively with the upper and lowerends of a drum 14 having an innor jacket 15. This communication is ef-'fected by means of the pipes 16 and- 17 respectively. These pipes leadto the space between the inner and 'outer'drums and this space is keptfilled with water sothat con stant circulation is maintained the hotwater rising through the coil 11 and passing into the space between thedrums through through the drum.

Within the space between the'inner and outer drums there is also 'acoiledpipe 17 which passes out through a suitable stuffing inthroughjthe wall of the inner drum by means of asuitablefitting 19.Within the inner drum this pipe is connectedto a ring 20 0f suitablepiping having openings 21 in I Patented Dec.17,1912. Application filedJanuary 3, 1912. SefialNo. 669,262. a I p if boX at'the' bottom ofthe'drum and passes the" bottom thereof. Passing downward through the upperhead 22of the drum is a i pipe 23 which terminates in an inverted funnel24: lying just below the ring 20 so ithatas the fluid passes from theopenings 21 it will be distributed evenly around the edges :of thefunnel 24. This pipe 23 leads I to thesteam chest or valve chest 24"of:an

ordinary Jsteam engine, .7 the. exhaust from whichpasses out through apipe 25. This pipe 25 communicateswith the interiorof a drumfhaving aninner cylinder 26 and an outer cylinder 27 and on the lower end of thepipe 25 where it passes through the head 28 of the last-"mentioned drumthere is fitted an inverted funnel 29 around the edges of which issecured'axeylinder 30 of suitable open mesh fabric. Leading through thehead 28, is'a second pipe 31 which terminates within the cylinder 26*inaring 32 rovided with suitable openings 33 so that o I the fluid passingout-of the ring will flow with inlet and outlet pipes 37 and 38' so Ithat a constant flow of cold water may be kept in constant circulationabout the inner cylinder 26, water'being supplied from city.

water works or any other of supply, I p v o Within the inner drum-15there is placed aqua'ntity of the compound which has the propertyofabsorbing gas at low temperaconven'ient source tures and giving off saidgas by the applica tion of heat. Many of the ammoniumcompounds possessthis property'a'nd ammonium' sulfo-cyanid has been found satisfactory.in

practice. This compound has theproperty of absorbing oroccluding'anhydrous ammonium gas when cold. The same compoundfis alsoplaced the cylinder 26 and the balance of the system is filled with anhydrous ammonium gas. Now as the cylinder 26 is kept cold by watercirculating about it the ammonium sulfo-cyanid will absorb gas in thiscylinder. From there it is pumped together with the gas of occlusionthrough the heater 32. As the coil 11 is kept constantly hot by thecirculation of exhaust gas or the like the jacket surrounding the drum15 will, in like manner, be kept hot so that the ammonium sulfo-cyanidin this latter drum in passing down through the pipe 38 is heated andparts with a certain portion of its heat to the fluid which is passingthrough the pipe 34. The fluid thus enters the coil 17 warm to a certainextent so that when it flows down through. the openings 21 it is incondition at once to give off anhydrous ammonium gas. This latter passesthrough the pipe 23 and oper ates the engine, it being, ofcourse,understood, that the liquid flows down to the bottom in a thinsheet closely adjacent the wall so that the gas is all the more readilygiven off.

When the ammonium gas has been used it then flows through the pipe 25and out of the funnel 29. At this time, however, the heated ammoniumsulfo-cyanid is flowing out of the openings 33 and trickling down themesh fabric where it comes into intimate communication with the ammoniumgas. As the sulfo-cyanid cools while passing over the fabric theammonium gas is again absorbed and the cycle thus becomes a recur ringone. It is to be understood that the pressure developed in the drum 15is not only suflicient to run the engine but alsoacts to force the fluidout of the bottom part of the drum and lift it to the top of thecylinder 26.

By properly pro-portioning the various parts the exhaust steam or gasmay be utiinner cylinder, a ring at the upper end of i the innercylinder consisting of a perforated pipe and connected to the upper endof said coil of pipe, an outlet pipe connected to the upper end of theheating drum and extending into the inner cylinder, an inverted funnelcarried on the inner end of said outlet pipe and having its edgeextending below the perforated ring, and a second outlet pipe leadingfrom the lower end of the inner drum.

2. A cooling drum comprising an inner and outer cylinder in concentricdisposition, cold water inlet and outlet pipes communicating withthespace between said cylinders, an inlet pipe extending into the innercylinder and provided on its lower end with an inverted funnel, an openmesh fabric screen depending from the edge of said inverted funnel, asecond inlet pipe extending into said inner cylinder at the top thereofand communicating with a ring of perforated pipe arranged above theinverted funnel, and an outlet pipe extending from the lower end of theinner cylinder.

In testimony whereof I aflix my signature in presence of two witnesses.
